The LHC detectors are designed to find the SM Higgs. Low mass is covered by , ttH(bb), qqH(WW*,). A low mass Higgs has many accessible decay modes couplings measured.

HEPAP Subpanel Report recognizes the importance of the SUSY search at LHC. Mass coverage up to ~ 3 TeV -> either prove or disprove SUSY hypothesis.
Energy matters! One month at 1/10 design luminosity extends mass reach by a lot.
LHC experiments must be ready on “week one” for new Physics.

• The US is investing 531 M$, plus the efforts of many talented HEP physicists, in the LHC. The NP community may soon join.
• US physicists have achieved leadership roles in detector construction (e.g. R. Loveless – CMS ME), software and computing (e.g. D. Stickland – CMS SWC), and high- field superconducting quadrupole construction.
• It is essential to capitalize on that investment by ensuring that US physicists also play a leadership role in the analysis and publication of LHC data.

There are ~ 2000 HEP physicists (DOE+NSF), ~ 1500 experimenters. US LHC is presently ~ 300 and would need to redirect to ~ 600 grad students + postdocs + faculty. The US LHC community will be a substantial fraction of US HEP accelerator based experimenters by first beam.

LHC Planning for the PhysicsPlanning for the PhysicsPlanning for the PhysicsPlanning for the Physics
• The LHC schedule has slipped ~ 2 years. The US has maintained its schedule to complete in ~ 2005.
• SWC has already begun because U.S. physicists contribute to insure participation in the physics. The involvement is driven by the desire to do physics on day 1. In addition, considerable time is required to create and deploy the new, absolutely necessary Grid architecture.
• M&O has begun as needed in order to commission detector and accelerator systems built and delivered by the US. Again, we want to commission the detector to be ready for physics (for example a SUSY search) immediately after beam arrives.

The Construction Project is completing. The collaboration proposes to apply their expertise to LHC machine commissioning. Also they propose to develop Upgrades to extend the performance and physics reach of the LHC. These efforts give forefront research opportunities to US accelerator physicists and possibilities to extend US leadership in state-of-the art- accelerator technology, e.g. SC magnets.

significant investment in and are making a significant contribution to the construction of the LHC.
• Leadership in IR design and construction
• Boost to accelerator technology at US labs.
• We should exploit and extend this investment by continuing the collaboration with CERN into commissioning, operating, and doing R&D for upgrades for the LHC program.

• The RP includes design of new IR for a high luminosity upgrade of LHC.
• The US labs are uniquely positioned to take an early lead in R&D for high performance Nb3Sn quads.
• The quads to be delivered in 2005 were designed in 1995. For a 2015 installation, design and R&D should begin no later than 2005 and be complete by 2011.

US ATLAS has made resource loaded schedules for M&O, SWC, and Upgrade R&D. That planning leads to the US ATLAS RP Needs shown.
The current cost estimates exceed the funding guidance – or budget authority - from DOE and NSF (BA) shown for comparison.

LHC Cost Estimates for the RPCost Estimates for the RPCost Estimates for the RPCost Estimates for the RP
The US LHC community has carefully estimated and scrubbed the costs for the Research Program. The US ATLAS + US CMS + Accelerator community estimate that more than 80 M$ support is needed in FY07 and beyond. Present planning within the guidance provided in the Budget Authority delays R&D for upgrades, slows the SWC ramp up, and reduces the contingency fund to a level which limits management agility.

LHC HEP FundingHEP FundingHEP FundingHEP Funding
DOE HEP funding is ~ constant at ~ 700 AY M$. The US LHC community, a large fraction of all US HEP accelerator based physicists, requests of DOE ~ 25 + 25 + 10 AYM$ for US ATLAS, US CMS and the LHC Accelerator RP. From NSF the estimate is 10 + 10 + 0 AYM$. Clearly the LHC is a great bargain.

The guidance – or Budget Authority - on RP funding means we must delay Upgrade R&D. Additional U.S. funds will also be needed after the R&D to upgrade the LHC and its detectors if the U.S. is to provide its appropriate share.

In general mass reach is increased by ~ 1.5 TeV (25 %) for Z’, heavy SUSY squarks or gluinos or extra dimension mass scales. A ~ 20% measurement of the HHH coupling is possible for Higgs masses from ~150 to 200 GeV. However, to realize these improvements we need to launch the necessary accelerator R&D and maintain the capabilities of the LHC detectors by upgrading them in a modest fashion.

LHC SummarySummarySummarySummary
• The Physics program available at the LHC is absolutely first class – with discovery potential and precision measurements possible.
• The technical edge given by advanced detectors, high field magnets and grid computing enables the LHC program and its US participants to stay on the frontier of our science.
• US physicists are in leadership positions in the LHC. This is made possible by the DOE/NSF investment.
• The gains realized from US investment are, and will continue to be, a great bargain.
• In order to realize that benefit, there must be sustained attention to the Research Program. Strong participation in the Physics analysis and Upgrades are crucial if the US is to maintain its leadership.
